We report the case of an 81-year-old man, with a spinal onset ALS, who was admitted to our clinic to start NIMV because of respiratory involvement. After 3 weeks from NIMV performed at night time, with beneficial effects, he suddenly complained of breathlessness even at rest and in standing position.
Diagnosis:
Respiratory and cardiac assessments did not show new clinical events, indicating the worsening respiratory function. Due to a history of osteoporosis which was treated with biphosphonates and even though no previous bone trauma or falls were reported, we performed a spine computed tomography scan. The findings in...

Talking, conversing, exchanging words: for more than 10 million people, this seemingly simple act cannot be imagined without assistive technologies, such as voice generating devices, touch screens or text-to-speech apps. What does the digital future bring for them? How could innovations turn around the translation industry or the medical administration process? Here’s a glimpse into the future of voice and speaking.
Speaking, identity, voice stereotypes
Give me the key! – This simple sentence carries much more information when it’s pronounced. A weary Philippino mother could instruct her little child as s...

The purpose of this study was to assess the sonoelastographic features of four different muscles in patients with amyotrophic lateral sclerosis compared with healthy controls and to evaluate the relationship of these features to muscle strength and other ultrasonographic variables. Fourteen patients with amyotrophic lateral sclerosis and 20 controls were examined using strain sonoelastography scanning. The RGB channel fraction ratio was analyzed with ImageJ software (Version 1.48). Two main sonoelastographic patterns could be distinguished in the controls: a clear predominance of the blue channel (hard areas) and a more he...

ConclusionsThe enlargement of the WTV found in the different MND phenotypes is attributable to the subcortical grey matter atrophy and is associated with cognitive and behavioural impairment. Larger longitudinal studies are needed to determine its role as biomarker in MND patients with frontotemporal dementia.

Scientists at the Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) have developed a method implemented as pulse sequences and software to be used with magnetic resonance imaging (MRI) scanners and systems. This technology is available for licensing and commercial development. The method allows for measuring and mapping features of the bulk or average apparent diffusion coefficient (ADC) of water in tissue – aiding in stroke diagnosis and cancer therapy assessment. The pulse sequences and software enable MRI scanners to yield diffusion weighted images (DWI) that are orientationa...

Abstract
Cannabinoid receptor CB2 (CB2R) is upregulated on activated microglia and astrocytes in the brain under inflammatory conditions and plays important roles in many neurological diseases, such as Alzheimer's disease, amyotrophic lateral sclerosis, and ischemic stroke. The advent of positron emission tomography (PET) using CB2R radiotracers has enabled the visualization of CB2R distribution in vivo in animal models of central nervous system inflammation, however translation to humans has been less successful. Several novel CB2R radiotracers have been developed and evaluated to quantify microglial activation. ...

Abstract
Neurodegenerative diseases can arise from a multitude of different pathological drivers, however protein misfolding appears to be a common molecular feature central to several disorders. Protein folding, and attainment of correct secondary and tertiary structure, is essential for proper protein function. Protein misfolding gives rise to structural perturbations that can result in loss of protein function or a gain of toxic function, such as through aggregation, either of which can initiate and propagate biological responses that are deleterious to cells. Several neurodegenerative diseases, such as Alzheim...
